ABSTRACT:
The present disclosure describes a low insertion force connector for use with integrated circuit (IC) packages of the LSI/VLSI type. The connector is characterized by simplicity of design and economy of manufacture. The well known friction-type contact comprised of members which enclose and bear against the pin surface is replaced by a pin-receiving cup loosely fitted in a cavity in the connector body and supported by one extremity of a light spring member. The opposite extremity of the latter may include an integral tail section or a separate solder or wire wrap tail may be affixed thereto. The force required to seat the IC package in the connector is a function of the spring compressive forces and may be made quite low. Removal force for the package is virtually zero. Additionally, a ramp section in the connector is adapted to receive a wedge-like member which bears against the outer surface of the IC package and causes the gradual collapse of the contact springs as the package is seated.
